The nurse hаs аn оrder tо аssess a client's residual urine. Which оf these actions is most effective?
Use the fоllоwing infоrmаtion to аnswer the questions below. You will need to show your work for these problems to get full credit. Be sure to uploаd your work for this problem alongside your cheatsheet. Your city has recently implemented a program where citizens can take a free financial literacy and retirement planning course through the local library. The city is now interested if the savings differ between those who participated in the course versus those who did not, and decide to conduct an observational study by comparing the savings of participants and non-participants. To do this, a random sample of 100 participants and 100 non-participants were surveyed, finding an average savings of $10,000 (Standard deviation of $2,500) and $9,000 (Standard deviation of $2,000) for participants and non-participants respectively. 1. What are your null and alternative hypotheses for this question? (1 point for 1 vs 2 tailed; 1 point each null and alternative hypothesis)? 2. Which of the tests that we went over in this section of the course would you use to evaluate this? (1 point) 3. How many degrees of freedom are associated with this test? (1 point) 4. What would the critical t-value be associated with this test for an alpha of 0.05? (1 point) 5. Calculate the t-statistic for this problem. (1 point) 6. Using your t-statistic and the critical t-value, is there a significant difference between these means at a 95% confidence level? (1 point) 7. Calculate the 95% confidence intervals associated with each of the samples above. You will be graded on the accuracy of your t-value(s) (1 point each), the standard error(s) (1 point each), and the resulting confidence intervals (1 point each). Hint: consider what your sample size(s) is(are) for these calculations. (6 total points) 8. Based on these confidence intervals, is there a significant difference between these sample means at a 95% confidence level? (1 point) Does this align with your answer from Question 21? (1 point)
